Add Stresses Dialog

The Add Stresses dialog for the HFB package

The Add Stresses dialog is accessed by clicking Add Rows in the Periods section of several MODFLOW 6 package dialogs. It contains the following sections and options:

• Table – Table Options differ according to each package. See chart below.

• Number of rows to add – Use the Increment Up and Down buttons to select the desired number of rows to add.

• Add to section – Radio buttons with the following options:
  • All defined periods – Select to add the rows to all defined periods.
  • Only this period – Select to add the rows to only this period.
